+Support IP_MULTICAST_IF socket option in linux-user
+Additional information:
+I've run into this limitation in qemu-aarch64-static version Debian 1:6.2+dfsg-2ubuntu6.12, but from the link above, it doesn't seem to be implemented on master yet.
+
+Here's some source code that demonstrates the failure:
+```
+#include <sys/socket.h>
+#include <arpa/inet.h>
+#include <netinet/ip.h>
+#include <unistd.h>
+#include <assert.h>
+#include <stdio.h>
+
+int main()
+{
+    int fd, ret;
+    struct in_addr addr = {htonl(INADDR_LOOPBACK)};
+
+    fd = socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP);
+    assert(fd >= 0);
+    ret = setsockopt(fd, IPPROTO_IP, IP_MULTICAST_IF, &addr, sizeof(addr));
+    if (ret < 0)
+    {
+        perror("setsockopt failed");
+        return 1;
+    }
+    close(fd);
+    printf("Success!\n");
+    return 0;
+}
+```
+
+When run under qemu, it gives the error `setsockopt failed: Protocol not available`.
+
+It doesn't look like it should be too hard to support (certainly no worse than IP_ADD_MEMBERSHIP). Let me know if I can help with a patch.
